An automotive driveline unit housing can be that of a power transfer unit (PTU), a final drive unit (FDU), or a rear drive unit (RDU). The automotive driveline unit housing has a lubricant feed passage spanning from an inlet to an outlet. The outlet can be situated near a seal of the automotive driveline unit, near a bearing of the unit, near both the seal and bearing, or near another component. The lubricant feed passage can have a flow restrictor located near its outlet. When the unit is in a connected state, lubricant is received in the lubricant feed passage via a spinning gear of the unit. The received lubricant trickles through the flow restrictor. And when the unit is in a disconnected state, lubricant continues to trickle through the flow restrictor, even though lubricant may no longer be received in the lubricant feed passage via the gear.

A lubricating assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of rotating machinery. In one embodiment, the lubricating assembly includes a bearing clamp member with a clamp body having an outer peripheral edge that has an annular profile that partially circumscribes a longitudinal axis. The annular profile can have first annular section with a first clamp surface and a second clamp surface disposed in opposing relation about a centerline and spaced apart from one another to form a first annular gap. At the bottom of the clamp body, the bearing clamp member is configured with a peripheral wall that bounds a reservoir region. This configuration allows the fluid lubricants to gravity feed through the first annular gap into the reservoir region to retain a volume of the captured lubricant to lubricate moving parts of the lubricating system.

A power transmission apparatus is capable of easily passing lubricant toward a seal arranged between a higher shat and an opening of a case of the apparatus. The apparatus includes the higher shaft, i.e., a hollow connecting shaft that faces the outside of the transfer case through the opening of the transfer case. The oil seal is arranged between the hollow shaft and the opening of the transfer case. The hollow shaft meshes, through helical spur gears, with an intermediate transferring shaft that is positioned lower than the hollow shaft. A lubricant guide is arranged to receive lubricant splashed up by the ring gear and helical spur gear of the intermediate shaft and guide the received lubricant toward the oil seal and a ball bearing.

A method of regulating the oil level in a section of an oil sump of a splash-lubricated transmission that has at least first and second oil sump sections that are separated by a baffle plate (2). The oil sprayed from a gearwheel (1), that is immersed in one oil sump section, is specifically deflected into an adjacent oil sump section.

A differential for a wheeled motor vehicle comprises a differential gear unit, and a differential case for housing therein the differential gear unit. The differential case is rotatable about its rotation axis in normal and reverse directions at a position above an oil level of a lubricating oil. The differential case includes a portion having an oil inlet opening formed therethrough, the oil inlet opening communicating the interior of the differential case with the outside of the same; and an oil dipping up structure that dips up the lubricating oil to force the same to enter the interior of the differential case through the oil inlet opening when the differential case rotates about the rotation axis.
摘要:
A motor vehicle transmission extension housing enclosing an output shaft rotatably supported by a bush at the rear end of the housing which requires lubrication is provided with an orifice for delivering a stream of lubricant under pressure from a source along a first unconfined path in the housing and against a deflecting surface in the housing which intersects the first path and deflects the stream of lubricant to flow along a second unconfined path at an angle to said first path and toward the bush.

An improved lubrication system for a two-stroke engine having a lubrication path from an oil sump directly to an induction valve assembly for noise reduction. The oil sump is divided into two chambers with a restricted passage therebetween to ensure lubrication of transmission gears upon startup while reducing drag during operation. A cross-drilled lubrication passage through each crankshaft throw terminates in a second passage proximate a dead-end plug, the second passage being in communication with the piston rod bearing. Each piston skirt includes at least one axial groove in registration with an oil supply passage. Circumferential grooves distribute the oil around the piston skirt from the axial grooves. The pistons may include ceramic top layers for heat insulation to increase the compression ratio possible by raising the ring positions. The engine incorporates an air/oil mixture separator within a balancer shaft chamber and air from the chamber is directed to the intake system.

The invention is directed to a transmission assembly comprising: a power output delivery end and a power input end; a pocket bearing operative between the power delivery end and the input end of the transmission; a lubricant containing housing remote from the pocket bearing in the transmission; a lubricant conduit system extending from said housing to said power input end of the transmission; a lubricant pump in said housing responsive to transmission operation for throwing lubricant outwardly under pressure within said housing; and a lubricant collector in said housing in the path of the lubricant thrown out by said pump, said collector directing the lubricant under pressure into said conduit system for delivery into said power input end of the transmission for supplying lubricant under pressure to reach said pocket bearing.

The lower part (11) of the chamber 8 of the geartrain (1, 3) has a profile substantially matching the peripheral outline of the lower gear, adjacent it, and forms a divider nose (12) connected flush to a discharge conduit (14) opening outwardly within an external container (16) the base of which communicates with the bottom part of the chamber (8) via an external conduit (22, 23, 25) including a restriction (26).

In a transaxle (1), a funnel-like oil pocket member (60) receives lube oil supplied from a gutter-like projection (43) formed to overlap a ring gear to collect oil sticking to a side thereof. The funnel-like member supplies lube oil to a lube oil passage (47) formed in a main shaft (18) through a hole (63) and a space (.delta.).
